Flicker fusion rate explains why time is perceived differently among different creatures. This is why it’s so hard to kill flies; time is perceived 600% slower for them.
A woman from the turn of the 20th century would sell people the time by letting them look at her watch. Ruth Belville, sold people the time. This was done by setting a Belville’s watch to Greenwich Mean Time, as shown by the Greenwich clock, each day and then “selling” people the time by letting them look at the watch and adjust theirs.
You experience your billionth (1,000,000,000) second of life during your 31st year.
Timeless physics is the controversial view that time, as we perceive it, does not exist as anything other than an illusion. Arguably we have no evidence of the past other than our memory of it, and no evidence of the future other than our belief in it.
In October 1971, a physicist and an astronomer took 4 cesium-beam atomic clocks aboard commercial airliners. They flew twice around the world and when reunited, the sets of clocks were found to disagree according to the predictions of the relativity theory. So, Einstein accurately predicted that time moves more slowly the faster you travel.
Time seems to speed up as we get older because each year we live is a smaller percentage of the total amount of time we’ve been alive. It’s called proportional theory.
There’s a suggestion that our perception of time may be in proportion to the length of our lifespan. Known as the “proportional theory”, this idea posits that as we age, our sense of “present” time begins to feel relatively short in comparison to our entire lifespan.
The ‘Time Cube’ is a conspiracy theory in which modern education and physics are hiding the ultimate truth: That each day actually consists of four separate simultaneously occurring days.
Three physicists flew around the world twice in 1971 with synced atomic clocks to test out the time dilation theory. Upon meeting up, they found that all 3 of the clocks disagreed with each other.
Due to gravitational time dilation the core of the earth is approx. 2.5 years younger than surface. Higher gravitational potential causes time to move faster. For example, over the course of earth’s history, a clock at the top of Mt. Everest would be approx. 39 hours fast than at sea level.
In medieval years, an hour was divided into 4 puncta (quarter-hours), 10 minuta, or 40 momenta. So if you asked someone to “wait a moment”, turns out that you really asked them to wait for about 90 seconds.
